利用相对密度、残炭值和馏出温度计算结构族组成

Calculation of structural groups based on density,carbon residue and boiling point

文中整理了20套原料油的分析数据,通过拟合的方法,得到了折光指数和相对分子质量与原料油的相对密度、残炭值和50%馏出温度的关联式。利用关联式可以对炼油厂的常规分析数据(包括密度、残炭值、50%馏出温度和硫含量)进行计算,得出原料油的结构族组成。

20 analysis analytical data of feed stock properties were collected.Through fitting method,correlations for calculating the refraction index and relative molecular mass were deduced according to the conventional analysis data of feed stock including density,carbon residue and boiling point at 50% as well as sulfur content.Thus,the structural groups can be figured out with conventional analysis data of feedstock.
